List with in a List PropertyInfo get properties iteration

I had a list as ProductSpec {id, Name} and another list as Product {productspec, id, Name}. When I try access the properties of Product into 

IList<PropertyInfo> properties = typeof(Product).GetProperties().ToList();

I am retreving my id and name as a property which is fine but when I try to reiterate a productspec as

foreach(var property in properties)
{
    IList<PropertyInfo> properties = property.propertytype.getproperties();
    // I am not getting the productspec columns 
    //instead I am getting (capacity,count ) as my properties..
}

So how do I reiterate a list from a list to get the list properties

You need to use same code for property type:

var innerProperties = property.PropertyType.GetProperties().ToList();

Also rename result - it conflicts with variable in foreach loop.

Is the type of the ProductSpec in the Product class of type ProductSpec or of type List<ProductSpec>? If it is a list you could do the following:

var properties = new List<PropertyInfo>();
foreach (var property in properties)
{
    if (typeof(IEnumerable).IsAssignableFrom(property.PropertyType)
        && property.PropertyType.IsGenericType
        && property.PropertyType.GetGenericArguments().Length == 1)
    {
        IList<PropertyInfo> innerProperties = property.PropertyType.GetGenericArguments()[0].GetProperties();
        //should contain properties of elements in lists
    }
    else
    {
        IList<PropertyInfo> innerProperties = property.PropertyType.GetProperties();
        //should contain properties of elements not in a list
    }
}

Try this:

    PropertyInfo[] propertyInfos = typeof(Product).GetProperties();
        foreach (var propertyInfo in propertyInfos)
        {
            var inner = propertyInfo.PropertyType.GetProperties().ToList();
        }

public class Product
{
    public ProductSpec Spec { get; set; }

    public string Id { get; set; }

    public string Name { get; set; }
}

public class  ProductSpec
{
    public string Id { get; set; }

    public string Name { get; set; }
}
